**hypercube_integrals**,
a FORTRAN90 code which
returns the exact value of the integral of any monomial
over the interior of the unit hypercube in M dimensions.

The interior of the unit hypercube in M dimensions is defined by

0 <= X(1:M) <= 1.

The integrands are all of the form

F(X) = product ( 1 <= I <= M ) X(I)^E(I)where the exponents are nonnegative integers.

**hypercube_integrals** is available in
a C version and
a C++ version and
a FORTRAN90 version and
a MATLAB version and
a Python version..
